Problems solved by technology

Cotton seedlings often use pond mud as the substrate of the seedbed. This kind of substrate is simple and easy, and the seedling raising effect is good, but the nutrient composition of the pond mud substrate is single, the salt-alkaline resistance is poor, and the water retention is insufficient.
[0003] my country's cotton production areas are generally located in the dry and barren Northwest and Southwest regions. The hydrological conditions in these regions are poor, but the light and heat conditions are good, which is suitable for planting dryland crops. However, for some lands with serious salinization, the survival rate of cotton seedlings Cotton production is also severely reduced

Embodiment 1

[0022] A culture substrate for raising salt-alkali-resistant cotton seedlings. According to the mass parts, the culture substrate includes the following components: 30 parts of garden soil, 5 parts of vermiculite, 4 parts of carbonized sawdust, 15 parts of peat soil, and 5 parts of coconut silk fiber 3 parts, 3 parts of vermicompost, 7 parts of calcium-based bentonite, 6 parts of hydrolyzed polyacrylonitrile, 3 parts of organic acid, 0.5 part of quick-acting fertilizer, 0.7 part of beneficial bacteria, 2 parts of organic SAP, 1 part of humic acid water retaining agent.

[0023] In this example, the preparation method of carbonized sawdust is as follows: the sawdust produced after sawing living trees is collected and put into a retort for carbonization treatment. The carbonization temperature in the retort is 250°C, and the charcoal obtained is pulverized. The mesh of the charcoal powder is 150 mesh. At the same time, the condensed recovery liquid produced during the carbonizati...

Embodiment 2

[0027] A culture substrate for raising salt-alkali-resistant cotton seedlings. According to the mass parts, the culture substrate includes the following components: 40 parts of garden soil, 8 parts of vermiculite, 7 parts of carbonized sawdust, 20 parts of peat soil, and 6 parts of coconut silk fiber 4 parts of vermicompost, 10 parts of calcium-based bentonite, 9 parts of hydrolyzed polyacrylonitrile, 5 parts of organic acid, 1.5 parts of quick-acting fertilizer, 2 parts of beneficial bacteria, 3 parts of organic SAP, and 3 parts of humic acid water retaining agent.

[0028] In this embodiment, the preparation method of carbonized sawdust is as follows: the sawdust produced after sawing living trees is collected and put into a retort for carbonization treatment. The carbonization temperature in the retort is 300°C, and the charcoal obtained is pulverized. The mesh of the charcoal powder is 180 mesh. At the same time, the condensed recovery liquid produced during the carbonizati...

Embodiment 3

[0032] A culture substrate for raising salt-alkali-resistant cotton seedlings. According to the mass parts, the culture substrate includes the following components: 35 parts of garden soil, 7 parts of vermiculite, 6 parts of carbonized sawdust, 18 parts of peat soil, and 5.5 parts of coconut fiber 3.5 parts of vermicompost, 9 parts of calcium-based bentonite, 8 parts of hydrolyzed polyacrylonitrile, 4 parts of organic acid, 1.1 parts of quick-acting fertilizer, 1.5 parts of beneficial bacteria, 2.5 parts of organic SAP, and 2 parts of humic acid water retaining agent.

[0033] In this embodiment, the preparation method of carbonized sawdust is as follows: the sawdust produced after sawing living trees is collected and sent to the retort for carbonization treatment. The carbonization temperature in the retort is 280°C, and the charcoal obtained is crushed. The mesh of the charcoal powder is 160 mesh. At the same time, the condensed recovery liquid produced during the carbonizati...

Abstract

The invention relates to the technical field of crop seedling cultivation, in particular to a culture medium for saline-alkali tolerant cotton seedling cultivation. The culture medium comprises gardensoil, vermiculite, carbonized saw dust, peat soil, coconut shred fibers, wormcast, calcium bentonite, hydrolyzed polyacrylonitrile, organic acids, quick-acting fertilizers, probiotics flora, organicSAP and a humic acid water-retaining agent. The carbonized saw dust is a product of fresh saw dust subjected to dry distillation, condensate mixing and fermentation composting, and the quick-acting fertilizers contain alkali-hydrolysable nitrogen, rapidly available phosphorus, rapidly available potassium and compound trace element fertilizers; the organic acids include glacial acetic acid, citricacid, polymaleic acid and oxalic acid; the probiotics flora includes bacillus laterosporus, phosphorus-solubilizing bacteria, gram positive actinomycetes, lactobacillus and rhodopseudomonas palustris.The culture medium can be used as a seedbed medium for saline-alkali tolerant cotton seedling cultivation, and drought tolerance and saline-alkali tolerance of cotton can be improved after seedling transplanting.

Description

technical field [0001] The invention relates to the technical field of crop seedling raising, in particular to a culture substrate for raising salt-alkali-resistant cotton seedlings. Background technique [0002] Cotton planting is mainly carried out by means of seedbed cultivation and strong seedling transplantation. This planting method can improve the utilization rate of seedlings, and the seedlings can be selected for breeding, thereby increasing the cotton yield per unit area. Cotton seedlings often use pond mud as the substrate of the seedbed. This substrate is simple and easy to raise seedlings, but the nutrient composition of the pond mud substrate is single, the salt and alkali resistance is poor, and the water retention is insufficient. [0003] my country's cotton production areas are generally located in the dry and barren Northwest and Southwest regions. The hydrological conditions in these regions are poor, but the light and heat conditions are good, which is s...
